Ideal for both interior and exterior use, this 1-gallon waterproofer provides reliable protection for basements, foundations, concrete block, stucco, brick, swimming pools and more.

Whether you’re tackling a damp basement wall or waterproofing an above-grade retaining wall, Drylok’s tintable white formula covers 75–125 sq ft per gallon and dries to the touch in just one hour.
